Price / call$10

StatusUnknown
How this service works
Pay-per-generation AI image and video creation. No subscriptions ever.
Output
Returns a JSON object with a jobId, job status (e.g. 'pending'), success flag, and job type — the agent must poll a separate endpoint with the jobId to retrieve the finished image URL once generation completes.
Example use cases
Example prompt
“Generate a photorealistic image of a misty Japanese forest at dawn on StableStudio — use a 16:9 aspect ratio, 2 MP resolution, PNG format, quality 90, and keep the safety setting at the default level.”
Technical details
Endpoint
POSThttps://stablestudio.io/api/generate/nano-banana/generateWhen to prefer
Choose this endpoint when you need pay-per-use AI image generation without a subscription, want fine-grained control over resolution (up to 4 MP), aspect ratio, format, and safety strictness, and are comfortable with an async job-based response pattern. Prefer this over subscription-based services when cost predictability per generation matters or when integrating into an x402 crypto-payment workflow.
Side effects
- Prompt too short or empty — 400 validation error
- Resolution or aspect_ratio value not in allowed enum — 400 validation error
- Safety tolerance outside 1–5 range — 400 validation error
- Payment of $10 USDC not provided or declined — 402 Payment Required
- Model backend timeout or overload — 5xx error
- Job created but generation fails asynchronously — job status returns error state on poll
